lM P ROVEM ENT IN PICTURE-TABLETS.

Specification forming part of Letters Patent No. 217,797, dated July 22, 1879; application filed May 9, 1879.

To all whom it may concern.- graphpaper. For other analogous purposes Be it known that I, CHARLES E. KELLOGG, of Elmwood, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements pertaining to Picture-Tablets, of which the following is a specification, reference being had to the accompanying drawings, where- Figure l is a view of one of the tablets. Fig. 2 is a view of the same in section, with parts shown somewhat enlarged.

The invention resides in the production of a tablet, bed, or groundwork for painting, photographs, sketching purposes, and the like, which shall not be subject to the disadvantages of warping, breaking, damage by water, destruction by moths and other insects, and easy decay, incident to the use of the materials commonly used for the purposes mentioned.

In the drawings, the dotted line a denotes what I will term the color-surface, which, foroil-paintings,niay be a painted and stippled surface, for water-colors it may be a layer or surface of granulated paper, and for photographs may be the properly-prepared photoused, thereby attaining oheapness of production and a tablet of little weight.

The preferable mode of uniting the metal plate and paper-board is to turn the edges of the plate over the paper-board.

WVhat I claim as my invention is The picture-tablet composed of the combination of the iron plate, the superimposed color-surface, and the paper-board back, all substantially as and for the purpose described.
